Why does warm weather decrease the range of an electric vehicle?
Batteries have to supply the power needed to keep the interior of the vehicle cool Batteries must supply power to help keep the batteries themselves cool Batteries do not function well at high temperatures All of these
HCCI is a process that eliminates what parts or components in a gasoline engine?
Battery Fuel injectors Fuel tank Ignition system
Which data parameter is often NOT included on the data stream of a scan tool when testing the high-voltage battery pack?
Battery voltage Battery temperature Battery current draw Type of battery
When working around high-voltage batteries, what precautions should be adhered to?
Be sure to disconnect the HV battery and allow enough time for system capacitors to discharge before proceeding. ALWAYS refer to the service manual for approved safety procedures when handling the HV battery pack. Do not work on the vehicle if moisture is present on the skin or anywhere on or near the vehicle. All of these
Which is NOT a function of an ultracapacitor?
Can pass DC current Can be charged with DC current Discharges DC current Can pass AC current

Why do cold temperatures reduce the range of an electric vehicle?
Passenger compartment heating is a concern for an electric vehicle because it requires the use of resistance units or other technology that reduces the range of the vehicle Cold temperatures reduce battery efficiency Additional electrical power from the batteries is needed to heat the batteries All of these
Which battery type is NOT being used in hybrid or electric vehicles?
Sodium-metal-chloride (ZEBRA) Zinc air Sodium sulfur All of these
What does H70-T40 mean when describing a hydrogen filling station?
The estimated time needed to fill the tank The temperature and pressure rating The type of hydrogen The size of the storage tank
Why must the charger cord be unreeled and laid out in a straight line when charging an EV or a PHEV?
To prevent electromagnetic interference To prevent heat buildup in the cable To allow the current to flow faster to the vehicle All of these
How is the high-voltage (HV) battery charged in a plug-in hybrid electric vehicle (PHEV)?
Using the ICE to turn the motor/generator to fully charge the HV battery Can be charged to full capacity by using a special dealer-only high-voltage charger Using an external charging station or electrical outlet Operating the ICE at idle after returning from a trip
